Be it known that I, JOHN A. WILSON, a citizen of the United States, residing at Elizabeth, New Jersey, have invented cer'-" tain' new and useful Improvements Coated Fabrics and Processes of Producing the Same, of which I declareithe to be a full, clear, and exact description.

s This invention relates to improvements in coated fabrics and the process of producing This invention relates particularly to water-proof fabrics, of the type sometimes nown as rubberized fabrics, manufactured by coating fabric with rubber, then vulcanizing the rubber coating so as to produce a coated fabric which is entirely water proof, may be subjected to considerableflexing or bending Without damaging the coating, and is suited for use in-many places, and particularly as an automobile top material.

One of the chief objects of my invention is to provide a water-proof-fabric in which qualities are improved, and

the water proof which more distinct figure. Another object of my invention 'isfto improve, simplify and cheapen the production ofsuch fabrics.

Further objects, and objects relating details and economies of production, will definitely appear from the detailed description to follow. In one instance, I accomplish the objects of my invention .by the means described in the following specification.

producing rubber coated to apply a coating of rubber, or rubber compound, to a textile fabric, such as a cotton drill for example. This rubber co'ated fabric then has starch sifted or sprinkled. over it, and is run between hot embossing rolls figure in the rubber coating. on the fabric. The rubber coated and embossed fabric is then Vulcan ized in a rubber heater in the mannen well own this art. It appears that the ruband therefore, applied to prevent the rubber from sticking;

'66 t9 the embossing rolls. T. e ct h t 1 16 9" Specification of Letters EPatent.

following I Patented Sept. 7,1920, 9, 1919. Serial No. 346,160;

rolls are hot tends to make the rubber stick more than .it naturally would. he use of this starch is very objectionable in the factory, as the air is filled with'it, and it does not entirely prevent the sticking of the rub- 6o 'ber to the embossing rolls if they are as hot i be desirable. accomplish the objects of my invention by applying what I term a clear, vulcanizing varnish to the unvulcanizedrubber coated fabric, befone it is passed through the em-. bossing rolls, and thenv'ulcanizing the rubber coating varnish taneously. Thls renders and it is eliminated.

- n practice, I coat textile fabric, such, for example, as a cotton drill, with a rubber solution'of t e proper composition and consistency, the composition of this rubber solution orming no part of my present invention. After this coating of rubber is applied to the fabric, 1 apply a coating of a liquid composition made up y pounds of sulfur to about 25 d oil, cuts, and

prevents the rubber from rolls during the embossing process,

embossing rolls may be hotter so as a'more distinct figure to the fabric. passing through the'embossing rolls, the fa where it is festooned and vulcanized by heating to about 240 F. for about two and a half to three, 'hours. If desired, another'luster coat of varnish maj be applied after embossing before vulcanizlng. After he ing vulcanized, this water-proof fabric is t up in pieces and rolled for shi men-a j have described. what I can1z1ng varnishmade of oil, cottonseed oil, and

that the rubb seed {will be noted the vulcanizing -ously,and, this is varnish which is applied to both vulcanized simultaneimportant because, if the rubber coating 1s vulcanized and a vulcanizthe coating are ing varnish applied, which is'later vulcanized, this causes a double vulcanization of the rubber coating, with the result thatit is over-cured and'deteriorates.

Having thus described my invention,

what I claim as new and desire to secure by Letters Patent, 1s:-
